Partial optical sighting device

Abstract

Apparatus, assemblies, and methods for sighting objects disclosed. A sighting device includes a segmented optic and a reticle. The reticle is optically aligned with the segmented object and is magnified by the segmented optic. A body structure supports the segmented optic and the reticle to define an open sight construction. In another aspect, a sighting device includes a segmented object and reticle, where the reticle includes multiple distance indicia and a contrast component. A support structure supports the reticle and the segmented object for magnification of the distance indicia by the segmented optic. A segmented optic in a sighting device is cut above center or otherwise such that a partial optic is defined having a portion above and below center. In another aspect, a sight adjustment mechanism includes a threaded connector that adjusts the sight position based on a difference between coarseness of threads engaged with the threaded connector.
